Crypto Automation
Trading bots and pipelines that survive reality
Exchange APIs, trading bot reliability, rate limiting, timestamp drift, WebSocket reconnection, and crash recovery — documented through source code, runbooks, and production failure patterns.
What you will find here
Everything your trading bot needs to survive production: exchange API reliability, rate limit safety, timestamp drift detection, WebSocket reconnection, crash recovery, and signature authentication — all documented through real failure patterns with runnable code.
Who this is for: engineers building or maintaining crypto trading bots on Binance, Bybit, Kraken, KuCoin, OKX, and Coinbase. If your bot has ever been banned, returned -1021, or duplicated an order after restart, this hub covers the fix.

WebSocket Reconnection That Actually Works: Auto-Reconnect Guide for Trading Bots
Complete WebSocket auto-reconnect guide for trading bots. Implement automatic reconnection with exponential backoff, heartbeat ping-pong, message gap detection, and state recovery. Production-tested TypeScript code included.
Crash Recovery: Reconciliation Loops That Prevent Double Orders
Build crash-proof trading bots with reconciliation loops that detect and correct out-of-sync state on restart—preventing double orders and orphan positions.
Bybit error 10006: params timestamp illegal — why it happens and how to fix it
When Bybit returns error 10006 "params timestamp illegal": why your trading bot's requests are rejected, the difference from Binance -1021, and the clock sync that prevents it.
Binance error -1021: timestamp for this request is outside the recvWindow
When your trading bot flips from working to "timestamp for this request is outside the recvWindow": why Binance rejects valid signatures after clock drift, and the time calibration that prevents -1021.
WebSocket closed with 1006: why trading bots lose connection without an error code
When WebSocket drops with 1006 abnormal closure and no close frame: why trading bots see 1006 instead of a clean close, and the reconnect strategy that handles it without guessing.
Trading bot keeps getting 429s after deploy: stop rate limit storms
When deploys trigger 429 storms: why synchronized restarts amplify rate limits, how to diagnose fixed window vs leaky bucket, and guardrails that stop repeat incidents.
